Paper Abstract

This paper describes the principles and methodology to express and calculate bi-directional reflection (BDR) parameters of ground targets by using radioactively decomposed remotely sensed image under the support ofGIS and DTM. The principles and theoretical basis are that the difference of slope and its orientation changes the relative position of pixel ground, sun, and satellite sensor and results in the variety of solar direct radiance of similar pixels. The differences reflect the bi-directional reflectance. The bi-directional reflectance could be studied through the analysis of the difference and its relation with sun position and satellite position under the support of GIS and DTM, using direct radiance digital images. Topics, covered in this paper, include calculation geometrical parameters of BRDF, on both slopes and plains and for both satellite and sun.
